guest@skeptic-os:~$ prove raglens
CLAIM a rag pipeline can be graded at the level of individual chunks.
EVIDENCE
attribution(C) = faithfulness(all chunks) − faithfulness(all − {C})
observed: removing one chunk moved faithfulness 0.42 → 0.89.
judge: a real llm on nvidia nim. no mocks, no scripted fixtures.
taxonomy shipped: retrieval_miss · chunk_dominance · generation_ignore.
INSTALL pip install raglens
SOURCE github.com/anujsingh-cse/raglens
VERDICT claim survives cross-examination.
guest@skeptic-os:~$ run orchestrator --adversarial
QUESTION do agents that argue merge stronger patches than agents that don't?
METHOD
coder proposes → adversary attacks → critic rules → human signs off.
control group: one agent, no debate. every session logged to sqlite, replayable.
budget: ₹0 — free nvidia nim tier; ollama drops in.
SIDE EFFECT
every broken patch is archived with full provenance.
the codebase calls this collection a "failure zoo". the name stuck.
ARTIFACT 124 tests · real bugs from real repositories
SOURCE github.com/anujsingh-cse/orchestrator-of-three-cycles
STATUS an experiment, not a product. it reports data, not opinions.
guest@skeptic-os:~$ audit ghostcoder
SUBJECT a coding assistant that does not trust itself.
FINDINGS
no sidebar, no chat — specialist agents whisper inline hints instead.
a skeptic agent re-reads every suggestion before it reaches you.
guardrails: rm -rf and DROP DATABASE never make it to the user.
`ghostcoder replay` reconstructs any session, step by step.
hardware floor: gtx 1650, 4 gb vram — the same machine this profile runs on.
INSTALL pip install ghostcoder
SOURCE github.com/anujsingh-cse/GhostCoder
RESULT scepticism, packaged: pip-installable.
guest@skeptic-os:~$ refute correlation
CHARGE charts keep claiming causation.
DEFENCE
identify → estimate → refute → sensitivity, all config-driven.
rosenbaum bounds · e-values · cinelli-hazlett · synthetic control ·
difference-in-differences · uplift modelling.
cli + streamlit console + one-command executive html reports.

RULING correlation remains innocent until proven structural.
guest@skeptic-os:~$ trace devrel-agent
TRACE issue.opened → intent classified → multi-file fix drafted
→ matching tests authored → diff self-audited

CASCADE gemini → nvidia nim → github models.

CONTAINMENT ENTRY — a diary that talks back
remembers what you write (postgres + chromadb)
responds as if it was always listening (llama-3.3-70b, nvidia nim)
promises secrets "that disappear", verbatim, on its landing page
deployed against advice — yes, it is live
an engineer of verification built the one machine you must not trust.
this is considered a feature of the collection. handle accordingly.

[ok] "pip install" lines checked against each project's own readme.
[ok] telemetry panel is generated by ci from the live api — never typed by hand.
[ok] repo count, last signal, uptime: computed at build time, see workflow file.
[warn] claim "class of 2026" is time-bounded. re-verification due july 2026.
[warn] the enchanted object remains enchanted. flagged weekly. no fix planned.
guest@skeptic-os:~$ sudo trust me
sudo: trust must be computed, not granted.
this incident has been logged — twice. the skeptic duplicates everything.
guest@skeptic-os:~$ refute anuj
grounds for doubt, offered without prompting:
· zero stars across the fleet at build time — adoption: unproven
· several experiments are young; replication is invited
· response latency scales with examination season
refutation declined. the subject agreed with you first.
